Getting started with the STM32 Nucleo and the sensor expansion
board X-NUCLEO-IKS01A1
Introduction
This document describes how to develop a sensor-based application using the STM32
Nucleo platform and the X-NUCLEO-IKS01A1 sensor expansion board, in the STM32Cube
software environment. The sensor expansion board is a multi-sensor board with
temperature, humidity, pressure and motion MEMS measuring sensors.

4.1.1 Initialization Every application must first execute the following basic initialization steps in order to configure and set up the STM32 Nucleo with the sensor expansion board hardware and the software stack for correct operation. Initializing STM32Cube HAL The STM32Cube HAL library must be initialized so that the necessary hardware components are correctly configured. -
Page 11: Application Description
AN4594 Guide for writing applications Reading data from sensor expansion board The BSP provides the API and the functionality for taking the data from sensors. Once the sensors are initialized we can get data from them using these functions: • BSP_HUM_TEMP_GetTemperature(float * Temp) This API gives the access to temperature sensor data. -
